Samsung 990 Pro 4TB NVMe SSD

The Samsung 990 Pro is a 4TB M.2 2280 internal solid-state drive built for desktop and laptop upgrades. It uses a PCIe 4.0 x4 interface with NVMe protocol to deliver high sequential throughput for demanding workloads. The drive targets creators, gamers and professionals who need large, fast storage in a compact form factor.

PCIe 4.0 x4 interface limits

This drive operates on the PCIe 4.0 x4 electrical standard, so its maximum bandwidth is defined by that generation. When installed in a PCIe 3.0 slot the drive will run at the slower generation's speed, reducing peak transfer rates. Motherboards without an M.2 key-M slot wired for four PCIe lanes cannot use this drive at all. Thermal throttling may occur under sustained heavy writes if the system lacks adequate airflow across the controller.

Straightforward M.2 installation

Installation requires an available M.2 2280 key-M slot and a single mounting screw; no cables or drive bays are needed. The most common issue is inserting the drive at an angle or forcing it into a key-B slot, which damages the connector. Another frequent problem is neglecting the motherboard standoff, leaving the drive unsupported and prone to connection loss. Ensure the BIOS is updated to recognise NVMe boot devices before cloning or installing an operating system.

Questions about this item

Should I choose the 4 TB 990 Pro or a smaller capacity?

The 4 TB model gives you the full 990 Pro performance envelope in a single M.2 2280 slot, avoiding the complexity of managing multiple smaller drives.

What does the PCIe 4.0 x4 rating actually deliver inside my PC?

PCIe 4.0 x4 lets the 990 Pro saturate the bus with sequential throughput that matches the interface ceiling, so large transfers and game loads run at the speed the slot allows.

Is the M.2 2280 NVMe interface compatible with my motherboard slot?

Any motherboard with an M.2 key-M slot wired for PCIe 4.0 x4 will run the 990 Pro at its rated link width and protocol without adapters.
